Product Description

 Description: HJ331 is a fused type medium manganese-oxide flux with vitreous granule of green color about 12-60 mesh in size. It is suitable for use with AC and DC power source.and it shows good welding usability, easy slag removal and smooth bead appearance.

Application: In combination with H08MnA,H10Mn2G(EH14) wires, this flux is suitable for welding carbon steel, low alloy steel and high tensile strength steel(such as A3,20G,16Mn,16MnR,A32,36,etc.) for ships and pressure vessel.

Guidelines For Usage:

1. Dry the flux at 300∼350°C for 2 hours before use.

2. Completely remove rust, oil and dirt from the groove surface prior to welding.

3. Arc voltage should be kept below 32V.
